I mean that "fun harmless in-crowd things" can be disturbing from the outside - context and intent matters. A strange in-crowd name is pretty far down the "there are harmless causes for this" side of things imo. Using it in a layoff announcement is probably not the best place though, unless they honestly think the laid-off feel good about it. A large enough package might achieve that tbh, but that's obviously rarely the case.

I'm honestly not sure if there exists a thing that a business can do that its employees would enjoy that will not be interpreted as creepy by some. Everything excludes someone somewhere somehow, the most you can do is target your crowd as best you can... and people commenting on a forum are not in that target audience, so I find the obsession over the name here to be pretty dumb. (Not claiming you're obsessed, just that it's the majority of the comments here so far)
